Any overclocking on, & are you using a "quality" PSU ?

Try memtest on the RAM, see if it brings back any errors just so you can rule that out.
Is anything shown when shutting down ? blue screen or anything ?
Anything overclocked ?

no overclocking, using a X-Pro 460W psu, will do a memtest....

"anything here suspect?" Yes, PSU. It maybe innocent, but it is lurking with possible intent to cause upset.

ok, so psu a possible suspect, anyway to test it? or best way process of elimination, just opened the pc and played made sure connections were proper and rebooted to get these voltages.....

i notice a few figures have changed? do these look any better, when i started the computer it did make a long beep... am just checking to see what this might mean

I know these s/ware voltage readings are to be taken with a large pinch of salt, but -16.97V on the -12V line seems excessive. To fault find is to swap components, & the first thing I'd beg or borrow is a PSU.
